Dinan Free Flow Exhaust

BQTuning · 05-18-2011, 07:34 PM

Today I got the Dinan free flow exaust installed. The sound on this exhaust is so incredible it humbles my heart when I start the car. Its a more bold, mature, and aggressive sound from the stock exhaust.

Benefits:

reduces back presure
increases power out put (6 hp / 5 tq)
better sporty sound
reduces overall weight

Cost: $1,599 after a $299.99 discount. {Currently now selling the stock muffler exhaust open to offers}

I cant say off top if I noticed are difference in power out put. I was cruising around most of the time just enjoying the sound

I will let the dyno this week determine that.

The sound on the Dinan FFE sounds alot better than the BMW performance exhaust and I believe better weight reduction also. In addition, I will be going with Dinan S3 flash that was developed to go with the Dinan FFE only and not the BMW performance.

The only thing I would get from the BMW performance is the bigger fan for the main radiator and the second rad if there is a way to get it to fit with the Dinan CAI.

I like it! Not too crazy loud, just about right like bmw pe.

That might be the best sounding exhaust for the N54 to date. And the price was spot on with your discount. I just wish the tips where a lil fatter, but that can be adjusted with $150. Nice exhaust.

I'd have to disagree.

The Dinan does sound good though and it's more "exclusive". Pretty cool to have the logo on the tips too

Congrats on the new exhaust.

Any problems running the Dinan exhaust system vs the OEM set up which included the tailpipe flapper?

Addendum - Just off the phone w/ Dinan. Answer is no, the software is programed to run w/o the extra back pressure.
